Answer:

6.75

Explanation:

2+10+1+8+12+6+23+5+8+4+4+3+2.59+5.11+5.18+9.07 = 107.95

now we count how much numbers you added up which equals 16 and divide it with 107.95

107.95/16 = 6.746875

now you cant pay half a penny or such and such

so your round it off at 6.746 to 6.75

and there you have it
